Math is unfamiliar and difficult
Fantasy math novels for teens and adults

In Volume 1 of 『Mathematics』, the main character is reincarnated into the Pythagorean and Euclidian eras.
The protagonist, who was reincarnated into the Pythagorean era, knows that the Pythagorean theorem has not yet been announced to the world, and tries to explain the existence of irrational numbers, but is at a loss as to how to prove it.
Although it is something he clearly learned in school, the protagonist, who finds himself unaware of even the approach to proof of irrational and rational numbers, learns the true nature of mathematics through the process of exploring and researching on his own, rather than studying for exams.

Everyone from liberal arts students, science students, math dropouts, and math nerds can read it!
Easier and more fun than any other math textbook

In keeping with the Fourth Industrial Revolution and the age of artificial intelligence, many books on "liberal mathematics" have been published, but actually reading them all is not an easy task.
If you haven't consistently thought mathematically, even a "liberal mathematics" book will be difficult to understand.
"Mathematics" is a book that uses the theme of "time slip" to create an immersive storyline and incorporates elements of romance, making it a book that anyone, even those who aren't confident in math, can read in one sitting.
Although the text contains mathematical content such as the Pythagorean theorem, prime and composite numbers, factorization, rational numbers, irrational numbers, and limits of functions, you can still read the book without understanding them.
The purpose of this book is not to impart knowledge, but to make you familiar with mathematics.
Of course, after reading to the end, you will remember the mathematical formulas and principles.
